This expert analysis, drawing on insights from a firearms instructor, reveals that not all AR-15 lower receivers are created equal, despite common perceptions. While many are forged similarly, significant differences arise from post-forge machining and rigorous quality control. Manufacturers like Bravo Company USA (BCM) invest heavily in these processes, leading to higher costs but greater reliability and in-spec components compared to cheaper alternatives like Palmetto State Armory (PSA). Understanding these differentiators is crucial for informed firearm building and ensuring long-term reliability.
